CVE-2025-10279: Privilege Escalation in mlflow/mlflow

In mlflow version 2.20.3, the temporary directory used for creating Python virtual environments is assigned insecure world-writable permissions (0o777). This vulnerability allows an attacker with write access to the /tmp directory to exploit a race condition and overwrite .py files in the virtual environment, leading to arbitrary code execution. The issue is resolved in version 3.4.0.

Root Cause Analysis

The vulnerability lies in the insecure permissions assigned to a temporary directory created by the mlflow library. The analysis of the provided commit patch pinpoints the exact location of this vulnerability. The commit 1d7c8d4cf0a67d407499a8a4ffac387ea4f8194a modifies the mlflow/utils/file_utils.py file. Specifically, within the get_or_create_tmp_dir function, the line os.chmod(tmp_dir, 0o777) is replaced with os.chmod(tmp_dir, 0o750). This change directly addresses the vulnerability by reducing the directory's permissions from world-writable to a more secure setting. Therefore, the get_or_create_tmp_dir function is the vulnerable function, as it was responsible for creating the temporary directory with insecure permissions.
